General Anaesthesia means that you will be completely asleep.
Induction of general anaesthesia for a Caesarean section however is not usually preceded by sedation because the agents can cross the placenta and depress the baby's ability to respond and breath when born. Oxygen is usually given to patients before induction, the bed tilted to the left and light pressure applied to the front of the neck to minimize the chance of stomach contents entering the lungs. In addition and antacid may be given before entering the theatre.
As you are going off to sleep an assistant will push on a specific area of the front of your throat (called 'cricoid pressure'), which blocks the top of the oesophagus to prevent aspiration of stomach contents.
